We don’t have a color temperature word for that, but “red” works. Of course, such light has no blue component (helps control the cicardian cycle) and is pretty much monochromatic with CRI of <5.

Personally though, something under 1500K is perfect for me as bedtime approaches. It primes me to fall asleep quickly

I’m not saying it’s a bad idea, I have a red bulb too. It’s “handmade” by removing thick red rubber from a “golf ball” decorative 7W CFL and stretching it over a similarly-sized 6W 2700K LED that has instant start and higher light output. It is not as monochromatic as pure red LEDs, I think it’s close to what the phosphor-based red ones emit but those are marketed as cicardian too. I have to avoid ooking straight into it though: the pupil is wide open because rods don’t react strongly to red light so long-wavelength (red) cones get massively overloaded and you see a green spot for a while.
